UPDATE
My SU CD suite's were just delivered. I had to try them immediately.
This is how to save then on a Mac to use in another program such as PSE
I could not just SAVE them after they were open . You may be able to just save on a Windows computer
On my Mac this what I did and it worked like a charm.
Insert CD into drive
Go to File--> Open
You get two choices
1. Double Click me to install ( that would be for MDS)
2. Extract for Other Applications.zip
I did the second choice.
There are several sets on each CD and each is in a folder after it unzips .
I dragged each folder to my desktop and then dropped them into my SU downloads file
As I said it worked like a charm. These CD suites EACH have 2-3 digi paper sets plus stamps and are a real bargain.
Hope this helps
